N.B.: The ?zeroDateTimeBehavior=convertToNull is pretty important--it
keeps MySQL's JDBC drivers from exploding when it encounters a date like
0000-00-00 00:00:00 (which technically shouldn't exist, but does in our
database).

If you don't know the username, password, or database name for your local
MySQL database, check the config/database.yml file for your checkout of
PFC.
